So I may be putting a lot of miles on the Jeep in the near future and I haven't replaced any fluids other than oils changes since getting it with 127k on it in February (it's got 138k now). It's probably a good idea to replace all the fluids in the driveline in preparation.
It's a 2007 Grand Cherokee Limited with the 5.7L Hemi and Quadra-Drive II full time all wheel drive with ELSDs. I'm thinking transmission fluid and filter change, front and rear differentials, and transfer case.
So do I go with all Mopar fluids, or splurge and use Redline? Or is there something else I should use?
